T0 all "whom ifmag concern 7- known th'atI, 'STA'NLExKRAsoN,

a citizen of Poland, having declared hisintention to become a citizen'fof the United States of America, "residing at Gary, in-the county of Lake and-State of Indiana, .have 1 invented certain- "newand useful- Improvementsin Bank-Boxes, of 'which the follow- The primary object" of the invention? the provision of a safety box or case fora whereby'he of a raid upon the bank or of the mail, the structure possessing greatstrength as well as being fire and bullet-proof.

A further object of the invention is to provide a box adapted for various uses whereby any object suddenly descending upon the floor thereof automatically releases the door for closing, to its locked position retaining the entrapped contents against the the same either by theuse of fire-arms or fire.

With these general objects in View the in vention consists of the novel combination and arrangement of parts hereinafter more fully described, in connection with the accompanying drawings and in which like reference characters designate correspond ing parts throughoutthe several views."

In the drawings,

Figure 1 is an el vention open,

Fig. 2 is a horizontal evational view of the'insectional View taken Fig. v3 is a front elevation of the invention closed partially broken away, Fig. 4 is a View similar to the lower portion of Fig. 1, 'with the door partially broken away showing the latch in place,

Fig. 5 is a vertical sectional view taken upon line V-V of Fig. 2,

Fig. 6 is an enlarged horizontal detail sectional view of the locking catch in position and Fig. 7 is a perspective View of an endpor- 7 tion of the latch employed.

My invention broadly consists of a box 10 triangular in horizontal cross section with one side 11 thereof in the form of a hinged door having closing springs 12 ad 13, the bottom 14 and top jacent its hinges 15 of the box'being in the form of an equilateral triangle.

A resilient latch 16 is secured as at 17 1 lspe cificati oxi cf Letters latent,

A false bottom or platform 23 triangular in shape rests upon coil springs 2 1 carried by the box bottom 14 and'upon the-deposit of any considerable weight upon the .platform 23, the platform s depressed, engaging the latch l6 and tripping the shoulder.

The door being released in thisv manner, the springs 12 automatically swing the door to its closed position where a plurality of spring catches 25- automatically engage over lugs26 uponthe adjacent edge of the box side and the door is locked in its closed position. The upward movement of the platform 23 is limited by inwardly projecting stops 27 upon the sides of the box, the operation of the release of the latch'l6 evident whether a weight packages or mail are thrown into the box or a person jumps into the box upon the platthe door 11' quickly springs closed retained bythe latches 25 and the box being formed of bullet-proof as well as fire-proof sheet metal, the obtaining of its contents from outside persons is extremelyjdifiicult. When aperson is located in the box however, the latches 25 may be released. by pulling inwardly upon the the catches 25.

The invention is simple'and strong in construction but capable of property in the event of rauders. A plurality of ventilating perforations 29 are provided through the sides of the box adjacent. the top. thereof.

While the form of the invention herein set forthis believed to be preferable, minor changes may be made without departing from the spirit of my invention.
